To me, it wasn't that her breast was visible. I am not offended by breasts, whether they are on Janet Jackson, or on the Spirit of Justice.

I was offended by the manner in which it was bared. Whether Jackson had consented to that part of the act or not (and the holes in her story imply that she did - does she always wear that silver nipple shield? It looks pointy and uncomfortable), the method of the baring of her breast implied sexual assault - a young thuggish male tells her that he's going to have her naked by the end of the song, and to do so, he rips off part of her clothing. Was MTV trying to imply that if you want to see someone's boob, it is ok to rip her shirt?
